电磁导航智能车检测和控制系统的研究

摘要

Signal detection, design and implementation of the control system of the electromagnetic navigation intelligent car are introduced. The magnetic field is analyzed on different path through Matlab, sensors ' arrangement scheme is determined. Follow-up signal processing circuit is designed on the acquired signals. The signal sampling is completed,and the control strategy is determined. According to the runway signal collected by the sensors, SCM analysis is carried out through A/D transformation. The speed of the car is controlled by incremental PID through pulse width control steering gear to realize corner turn of intelligent car. Finally the fabrication of the electromagnetic navigation intelligent car which can operate on different paths steady and- fast is realized.%对电磁导航智能车的信号检测、控制系统的设计和实现做了介绍.通过Matlab对不同路径进行了磁场分析,确立了传感器的排布方案,并针对采集的信号进行了后续信号处理电路的设计,完成了信号的采样,确定了控制策略,单片机根据传感器采集的跑道信号通过A/D转换进行分析,通过增量式PID来控制智能车的速度,并通过脉宽控制舵机转角来实现智能车的拐弯,最终实现了能够针对不同路径稳定快速运行的电磁导航智能车的制作.
